We learned that renewable energy sources include solar power, hydroelectric power, which is power generated by water and geothermal power, which is power created from heat within the Earth's crust. We also learned that non-renewable energy sources are unsustainable.
Lightning is a large-scale natural spark discharge that occurs within the atmosphere or between the atmosphere and the Earth’s surface. On discharge, a highly electrically conductive plasma channel is created within the air, and when current flows within this channel, it rapidly heats the air up to about 25,000°C.
